21st Century Niacinamida 500 mg Comprimidos de Liberación Sostenida - 220 unidades (Paquete de 2)

What is Niacinamide (Vitamin B3)?

Niacinamide, also known as nicotinamide, is a form of vitamin B3. Each 21st Century Niacinamide tablet provides 500 mg of this nutrient in an extended-release format, designed for gradual intake.

Why choose extended-release niacinamide?

The extended-release formulation gradually releases the active ingredient, maintaining a stable blood concentration for several hours. This optimizes absorption and reduces the likelihood of mild digestive discomfort that might occur with high doses of immediate-release forms.

Each package contains 110 tablets, and as it is a pack of two, you will have 220 doses. This facilitates long-term supplementation planning.

The 21st Century formula is manufactured under recognized quality standards, and the tablets are easy to swallow.

Recommended dosage and instructions for use

The manufacturer's recommended usual dose is one tablet daily, preferably with a meal. Do not exceed the recommended daily dose. Each tablet provides 500 mg of niacinamide. Tablets should be swallowed whole, without chewing, to preserve their extended-release mechanism. Store in a cool, dry place, out of reach of children.

Possible side effects and precautions

Niacinamide is generally well tolerated. Side effects are rare and usually mild, including gastrointestinal discomfort, nausea, or headache. Consult your doctor if you are pregnant, breastfeeding, or have any pre-existing health conditions. This product is a food supplement, not a medicine. It should not be used as a substitute for a balanced diet.
